To reproduce the problem simply use javaw on a non-existent jar example:
% c:/blah/javaw -jar some_non_existing.jar

The only workaround is for customers to retry the operation with java.exe.

The manifest file was added as a part of the fix for 6359035 (Apply WinXP visual styles to AWT native dialogs). It enables comctl32.dll version 6 to be used in runtime, probably, this new version of comctl32 has its own MessageBox routines?...

After a short investigation, I found that inserting a call to ::InitCommonCotrols() before ::MessageBox() solves the problem. To be able to call ::InitCommonControls() we need to include <commctrl.h> header file and link java launcher with comctl32.lib.
The proposed changes above should be done for javaw (and probably other executives), and at the same time the call to ::InitCommonControls() should be inserted to awt.dll. I hope two calls to this method are OK.

Using Windows Vista, jdk7 b19 the problem is not reproducible for me. The message box is shown when non-existing jar is specified.
